Shared APPL_TOP Headaches?

In my post about RAC on Loosely-Coupled Clusters I discussed how strange it is to me that RAC is a shared disk architecture yet RAC deployments are shared-nothing for everything except the database. I mentioned the concept of Shared Applications Tier as well. Arnoud Roth has a post about shared APPL_TOP on the AMIS Technology Blog that I recommend you investigate. It seems there are some gaps in the shared APPL_TOP methodology that I was unaware of. There are a lot of folks doing shared APPL_TOP so perhaps they were all simply willing to work through these issues. They are issues nonetheless and do warrant consideration.
